If your helper breaks expensive stuff is it fair to deduct their salary? The helper broke a $2000 vase which I said to be careful

I agree with the majority here - don't deduct her salary. At work, we are usually always given a stern warning first before we get penalize and I think it's only fair to extend that to domestic helpers as well. $2000 vase is an expensive piece to be losing and I can understand your pain but your vase is replaceable (I assumed since there's no mentioned of any sentimental value) but should you deduct her salary, it would only mean lesser money for her to send to her family. Less money, less food for her family back home. Give her a warning, but also be firm that there should not be a next time. I am sure she will be appreciative of the chance that will be given to her.
